I wonder how many Ford fans threw a blade "back in the day" ?

I think Skip has something about the blades flexing fore & aft as the engine speeds-up and slows down, and eventually the metal fatigues and cracks near the base of the blade.

I also have to wonder if running Model A's at generally higher speeds for prolonged periods of time than was possible "back in the day", on dirt roads, is partly responsible for increased fan-failure ?

Do these fans fail putting around town at 30 MPH, or out on the road at higher speeds ?
